MOLD FOB CASTING ORGAN-PIPE TOES.

Application filed December 17, 1927. Serial No. 240,766.

This invention relates to organ pipesand more particularly to the fitting of such pipes, or the foot pipes thereof, with the usual toe points in which the wind opening is formed.

According to the practice in vogue the toe pieces are separately cast and are subsequently soldered to the metal pipe. This is both expensive and leaves a ridge which is ob ectionable and entails several operations.

In accordance with the present inventlon the toe piece is cast directly on the metal pipe, whereby simplifying and materially reducing the cost of production and insuring a neat and smooth joint externally which is desirable and of advantage in the fitting of the parts when assembling.

For a full understanding of the invention and the merits thereof, reference is to be had to the following description and the drawings hereto attached, in which,

Figure 1 is a sectional View illustrative of an application of the invention.

Figure 2 is a perspective view of the component parts of the mold.

Corresponding and like parts are referred to in the following description and designated in the two views of the drawing by like reference characters.

The numeral 1 designates an organ pipe, or more properly speaking the foot pipe which is of metal and tapered throughout its length. The invention relates tothe means whereby the pipe has the toe applied thereto, said means consisting of a mold, which admits of the toe being cast directly upon the pipe, thereby obviating intermediate steps and materially simplifying and reducing the-cost of production, besides resulting in the provision of an article which is free from any ridge or welt opposite the joint formed between the toe and pipe.

The mold comprises a plug or body 2 which tapers slightly to conform to the taper of the pipe 1. A conoidal shaped tip 3 is formed on the outer end of the body or plug, as a part thereof, and terminates in a centrally disposed teat 4. A shoulder 5 is provided at the base of the tip 3 and defines the thickness of the base portion of the toe to be cast upon the pipe. A stem 6 projects from the end of the plug 2 opposite that provided with the tip 3 and is centrally disposed and is of a length to project beyond the end of the pipe 1. The stem 6 is threaded for some distance from its outer extremity, as indicated at 7 and receives a follower 8 and a nut 9, the latter serving to secure the follower 8 in the re quired adj usted' position. Adjustment of the follower 8 serves to properly position the plug 2 when adjusting the same to the pipe 1 preliminary to casting the toe thereon. The mold also includes a cope 10 which is formed in a side with a conoidal shaped recess 12, which conforms to the outline of the tip 3. The base portion of the recess 12 is-of a diameter to receive the end of the pipe 1. The cope 10 is provided with a handle 13 for c onvenience of manipulation. When the parts are assembled a space is formed between the tip 3 and the recess 12 which corresponds to the shape of the toe piece tobe cast upon the pipe 1. The teat 4 extends through the open-' ing 11 leaving a surrounding space through which the molten metal is poured in the process of casting the toe. The metal generally consists of a composition of lead and tinto which may be added antimony, bismuth and analogous alloy. After the mold has been assembled, as indicated most clearly in Figure 1 of the drawing, the molten metal is poured through the opening 11 and forms the toe 14 which is flush at its outer side with the outer side of the pipe 1, the base portion projecting slightly into the pipe and over the end thereof. The teat 4 projecting through the opening 11 results in forming the opening in the toe 14 which is subsequently enlarged, as oocasion may require in the voicing of the organ, or other musical instrument having the pipes installed therein. The mold, when adjusted, may be easily withdrawn from the pipe after the casting of the toe thereon and quickly applied to another pipe required to be fitted with the toe. It will thus be understood that the production is greatly simplified and the cost minimized and results in an article free from any ridge or projection opposite the joint formed between the toe and pipe. 7 p Having thus described the invention, I claim:

' 1. A mold for casting a toe upon a metallicorgan pipe, including a body provided with a tip forming a shoulder adjacent the body, and having a stem. extending therefrom in opposition to the tip and threaded for a distance from its end, a follower and binding the stem, and a cope adapted to coact with the tip portion of the body to form the mold space for the toe. 2. A mold for casting a toe upon a metal organ pipe, the same consisting of a tapered plug having a conoidal shaped tip surmounted by a centrally disposed teat, and having a stein projecting in opposition to the tip and threaded for a short distance from its end, a

follower and nut mounted upon'the threaded end of the stem, and a cope having a conoidal shaped recess in one side and provided With a central opening, the plug being adaptedtofit Within the pipe and the cope to extend thereover.

In testimony whereof I afiix my signature.
